Self-winding doll and mechanism



United States Patent O "ice 3,496,672 SELF-WINDING DOLL AND MECHANISM William J. Pipa, 1610 Gilford Ave., New Hyde Park, N.Y. 11040 Filed May 8, 1968, Ser. No. 727,513 Int. Cl. A63h 3/36 U.S. Cl. 46-118 1 Claim ABSTRACT OF THE DISCLOSURE This invention relates to a doll which is rocked to sleep, said rocking process suitably operating a pendulum to wind up an operating spring. The Wound spring upon denand operates various doll appenda-ges upon being reeased.

It is an object of this invention to provide a means for Winding up an operating spring in a doll while rocking the doll to sleep.

It is another object to provide a mechanism of simple yet rugged construction to accomplish the desired result.

These and other objects of this invention will become apparent upon reading the following description of an illustrative embodiment thereof and shown in the accompanying drawing in which FIG. l is a schematic View showing a doll in a reclining position with the winding and operating mechanism represented as an outlined box and showing by means of a curved line having arrows at each end the motion needed to energize a pendulum therein.

FIG. 2 is a section view taken on line 2-2 of FIG. l and showing the frame construction and the pendulum mounted therein and the pawl and ratchet means for winding up an operative coil spring, the energy of 'which is used on demand to make the doll legs move up and down using conventional kicking apparatus.

FIG. 3 is a view taken on line 3 3 of FIG. 2 and showing the detail structure of pendulum assembly including the pawl and ratchet means for energizing the coil sprlng.

Turning to the drawing, a doll is provided in the body portion thereof with a suitable substantially rectangular frame 11 having a front wall 12, a middle wall 13, a rear wall 14, a top wall 15 and a bottom wall 16.

A rod 17 is xedly disposed in walls 12 and 13 and a Wedge shaped pendulum 118 of suitable weight, for example, of lead is mounted for free swinging, using a conventional bearing, upon said rod 17.

The pendulum is provided on its rear face with a fixed pusher arm 19. A ratchet Wheel 20, having suitably slanted teeth 21 thereon, is mounted on rod 17 adjacent to Wall 13. Said ratchet Wheel is pushed counterclockwise one tooth or more With each push of arm 19 of the pendulum 18 (FIG. 3). Undesirable clockwise rotation of the ratchet Iwheel 20 is prevented by the spring loaded pawl 22 attached to frame 11.

The back surface of wheel 20 is provided with an in- 3,496,672 Patented Feb. 24, 1970 tegral hub gear 23 also disposed on rod 17. The gear 23 engages a large windup gear 24 fixedly secured to axle 24X, secured in turn fixedly to the center of coil or spiral spring 26X. The outer edge of the spiral spring 26X is fixedly secured to the inside surface of a cylindrical cupshaped band element 26 (see FIG. 2 showing pair of dotted lines indicating the spiral spring 26X and its edge).

An axle 25 is disposed in walls 13 and 14 and it is keyed to both gear 24 and to a suitably large band coil spring 26X. The rod 25 operates conventional kicking mechanism 28 to operate the legs 27 in a kicking manner.

To release the energized spring 26X on demand, a suitable release button is provided. This release button 30 engages a buttertiy pawl vane secured to rod 32 located in the base of walls 13 and 14. The gear 33 is secured to rod 32 and engages large gear 34 idling on rod 25. The buttery vane 31 retains the coil spring 26X in its energized condition until release is effected by the release button 30.

What is claimed is:

1. In a doll having a spiral spring for operating appendages thereof, the improvement comprising, a three wall two compartment frame suitably disposed in the body of said doll; a first rotatable rod disposed in the first compartment of said frame longitudinally of said doll; a free swinging Wedge pendulum disposed on said rod and adapted to oscillate While the doll is rocked to sleep; an arm fixed to said pendulum and adapted to advance a ratchet wheel one tooth at a time; a ratchet wheel and gear means rotatably disposed on said tirst rod; pawl means secured to said frame and engaging said ratchet wheel to effect one way rotation thereof; driven gear means secured to an axle disposed in the second compartment of said frame and engaging said ratchet wheel; said spiral spring being interiorly secured to and about said axle; cup-shaped cylindrical means disposed on said axle and enclosing said spiral spring and secured to the outer edge of said spring; a large gear free-mounted on said axle and lixedly secured to said cup-shaped means; a second rotatable rod and having a fixed gear at one end engaging said large gear; a butterfly vane fixedly secured to the other end of said second rod; and a release button suitably secured to the doll body wall and engaging said butterily vane whereby said spiral spring is wound up while rocking the doll to sleep and released on operation of said release button to actuate said appendages.
